Well, it might not do 200 mpg but I bet it is close. I just bought a pair of moped kits. One is for my wife's bike (which cost me $10 at a yard sale
) and the other is for my hybrid trike project. These kits are amazingly cheap at $145 US and are very well made. They include every single part needed including twist grip throttle and even a couple of maintenance tools such as a sprocket wrench and a sprocket puller for the engine. The engine is a 2 stroke 64.5 cc and is rated at about 1.6 hp. That seems to be a fair rating as it will pull my 200 lb arse up a 13% grade easily.

The one part of the kit that posed a problem of sorts is the chain. It is a super heavy duty #50 and would be much more suited to a 250cc motorcycle. It is also too loose in the links and every link needs to be punched together to reduce the play. Instead I spent another $7 on a #50 bicycle chain which is much more appropriate. I had to machine the thickness of the drive sprocket on the motor and the included tools worked perfectly for removing the sprocket.
This was another test of the cermet insert and it came through without damage. It didn't mind the interrupted cut at all and had no trouble with the hardened sprocket.

The engine is started by popping the clutch after pedaling up to a few mph and takes over immediately. It run very quietly and is pretty smooth for a single cylinder engine. It has a redline of about 6000 rpm but if you take it up there it begins to vibrate like a Norton Atlas with a twisted crank pin.
Up to around 4000 to 5000 rpm it's fine and it lugs way down low really well which surprised me.
This is really a test bed for my trike project and so far it is looking really good.
